I wasn't informed of anything until after the Havana was tangling with things in Delta.
After being knocked out of that fight, we moved ships into position, and were working out what to do about the BHG fleet that was on the move (as the rather substantial string of death messages scrawling across our screen was evidencing) Considering that just yesterday we shot down one of your battlecruisers, it isn't a stretch to expect attack...
in fact we were quite surprised when it went to Gallia, relieved even... then the Maquis messages...
